There’s hardly a guarantee that the Ike Davis who handled first base for the Pittsburgh Pirates a few days this weekend will hit any differently than the one that struggled so much last season for the New York Mets. The Davis who singled and doubled Saturday and singled in six at-bats Sunday didn’t look like a totally new hitter, though he probably felt quite a bit more comfortable with his new role. We need a bit more than a weekend to come to any true conclusions.
